METHODS OF AND APPARATUSES FOR IDENTIFYING GEOLOGICAL CHARACTERISTICS IN BOREHOLES |
摘要 |
A method of detecting an edge of a geological characteristic in a borehole comprises, in respect of an image log of a length of a borehole, carrying out the steps of a gradient-based edge detection method, a phase congruence-based edge detection method or a combination of such methods as preliminary, pre-processing stages. Subsequent steps of the method may include operating a relatively computationally simple process to identify sinusoids among detected edge features; and a relatively computationally complex process for parameterising the thus-identified sinusoids. |
